Here is a link to a Wiki on Dana 60s.

Dana 60 - Wikipedia

en.wikipedia.org

It says that Dana supplied rear axles to Ford along with several others. I had an old Bronco years ago and it had factory Dana axles on it.

Thanks for your info. Looks like Dana 44 or 60. Now I have to find the best combination for 347 stroker + gearbox + rear end...

8.8s positive traction rear ends are what came in fox body mustangs. At this point I've got to give a disclaimer. I tinker on cars and work on my fox and 65. There are guys on here that are actual mechanics and hot rodders. Hopefully someone with actual knowledge will take notice of this thread and step in. 200 for a decent 8.8 doesn't sound bad. I'm going to assume that you plan to rebuild what ever you get anyway. Thats what I would do before installing it as you have no idea of its internal condition.

As for installing it in a 68. I dont know. I think people do it. I would encourage you to search around for information on that specific swap. A quick glance at this old thread makes it sound like it is doable, but you need to make sure you know what you are getting into. Depending on what the 8.8 came out of can create some problems. According to this thread.

8.8 rear end swap

would an 8.8 rear end, measuring 53" from backer plate to backer plate, with disc brakes fit (without modification) on my 68 coupe?

@horse sence do you know anything about this swap?

What is in the car currently and why are you wanting to make the swap?

I saw where you posted a question in that old thread. You might get some action there, but its a really old thread so I doubt it. This thread will do. The classic section of this site doesn't see as much traffic as say the fox section, but there are some very knowledgeable people that frequent this section of the site. It could take a few days before you get more people chiming into this thread, but they will.

@wicked93gs might also be able to help with this question as well.

I haven't put any 8.8s in a vintage mustang...but on my last '66 I did actually have a 7.5" with rear disc from a Mark VII if I remember correctly? The 7.5 and 8.8 in the fox were the same width...you can fit a 8.8" from a foxbody in a vintage mustang, but the wheel offset will change(more dramatically for 65-66 than for 67-68) so if you do so...you may be forced to use later model wheels(which also means you will need spacers to use them on the front). One way around it is to shorten the 8.8", but then you get into custom length axles, etc. It really depends on what you need as far as strength goes and what wheels you are wanting to use with it. The best axle choice is going to vary from build to build. That being said...the 8.8" is an excellent choice if you need something that comes with factory LSD and rear disc brakes...but it will require work to properly fit a vintage mustang. The 8.8" you choose needs to be thoroughly researched as well.(If I were to do the swap myself, I would choose an 8.8" from an explorer, shortened on the passenger side, and using 2 driver's side axles, then run whatever spacers were required to correct the wheel offset....its the most well-known way to do it...but there are plenty of other ways. The best unit you could start with for example would be a 2014 Mustang GT 8.8"....since its new and easy to find, the clutch packs would be in good condition...the downside being that custom length axles would be required(pretty sure the explorer axles inner spline isnt the same as the late model mustang, but I could be wrong on that).

That being said, there are plenty of others out there that would be able to give you better details than me on the swap.
